Title: Three phase 180 degrees-type three pulse ring counter
Inventor: NAKAJIMA ARATA
IPC: G06F5/08
Filed: 1998-09-30
Abstract: PROBLEM TO BE SOLVED: To obtain a time base which can easily synchronize an input clock with a whole system by using the phase of the output of a register and outputting a rectangular wave whose one pulse of the 180 degrees rectangular wave of target use is 60 degrees and which generates conduction angles with one phase, two phases and three phases at two bit intervals from the first pulse. SOLUTION: A ring counter outputs continuous H and L shift feedings by three pulses from a shift register 4015 of dual four bits being eight bits in total and a dual four bit flop 4013. A flip flop or the shift register sychronized with pulse width modulation constitutes a three phase three pulse ring counter. Since the feeding shift of H and L can be executed by the cascade connection of the flip flop, a ring pulse can easily by controlled by feeding shift through the synchronization of input data where 1/3 pulse of a 180 degree rectangular wave can be generated with a clock. Since six diodes are opened/closed and the speed of a three phase motor is controlled by the cascade connection of the flop 4013, positive/negative output pulses are distributed by the rectangular waves of 180 degrees.
